A new program aimed at protecting Oregon waterways has already earned its keep. Border inspectors discovered a potentially damaging invasive species hitching a ride on a boat being towed into the state: “a boat came through the inspection station with some Zebra Mussels attached to the outdrive motor.” Glen Dolphin of the Oregon State Marine Board says those Zebra Mussels could have attached themselves to the plumbing of dams and drinking water supplies, doing significant environmental and economic damage.
